STOF-MOTION.

To all @07mm t may concern.'

Be it known that I, KARL SLoAT, a citizen of the United States, and aresident of Scranton, in the county of Laclrawanna and State ofPennsylvania, have invented a new and Improved Stop-Motion, ot which thefollowing is a full, clear, and eXact description.

The object of the invention is to provide a new and improved stop motiondesigned for use on reeling machines and similar machines, and arrangedto quickly and positively stop the reel in case ot' the breaking of athread or yarn, or the running out ot the yarn from its spool, whichrequires no line adjustment or sensitive balancing by skilled workmen,and to prevent the parts from beingl actuated by mere vibration incidentto the running et the machine.

In order to accomplish the desired result, use is made of a pivotedlifting arm adapted. to liftthe reel out of engagement with the drivinggear, pivoted drop arms having eyes 'for the threads or yarns to passthrough to normally hold the drop arms in raised inactive position, andactuating' means controlled by the said drop arms and controlling' thesaid lifting arm to move the latter into active position on the releaseof adrop arm by this thread or yarn.

A practical embodiment ot the invention is represented in theaccompanying drawings forming a part or" this speciication, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a side elevation of the stop motion as applied to a silkreelingmachine; Fig. 2 is a cross section ot' the same on the line 2 2of Fig. l; Fig. 3 is a similar view of the same with the parts inposition after a drop arm is released by its thread or yarn and the reelis stopped from rotating; Fig. 1l; is a sectional plan view ot' thesaine on the line 4 4 of Fig. 2; Fig. 5 is a cross section of part ofthe stop mot-ion and showing more particularly one of the drop arms indropped position; Fig. 6 is a cross section` of part ot the reelingmachine, the section being on the line 6-6 of Fig. l; and Fig. 7 is afront elevation of part of the mechanism for imparting a reciprocatingmotion to the actua-ting slide.

The reeling machine on which the stop motion is applied is mounted on asuitably constructed frame A in which is journaled a Specification ofLetters Patent.

main shait B provided at one end with a pulley B connected by a beltwith other machinery for imparting a continuous rotary motion to thesaid main shaft B. On the main shaft B is secured a driving pulley B2normally in frictional contact with the peripheral face of a pulley Csecured on the shaft D of the reel l) on which the threads or yarns Eare Wound, the threads or yarns unwlnding from suitable bobbins orspools E, as plainly indicated in Figs. l and 2.

The reel shaft D is journaled at its ends in open bearings A and A2 heldon the ends of the main trame A, thus permitting removal of the hlledreel from the machine and lifting of the pulley C out of drivingengagement with the pulley B2 to stop the rotation of the reel D andconsequently the Winding up of the yarns or threads E on the said reelin case a thread or yarn is broken or the thread runs out on a spool E',as hereinafter more fully explained.

Each ot' the threads or yarns E passes through an eye F of a drop arm Fnormally disposed in a vertical position and resting against a rod Grattached te the traine A and in front of which passes the correspondingthread E (see Fig. 2). The drop arm F is provided with a heel F2 pivotedon a bearing` ll attached to a shaft or rod lil mounted to slide in thedirection of its length in bearings A3, AJ* forming parts ot' the maintraine A. The shaft H isnor mally held in position, as shown in Fig. l,by the action ot a spring H2 resting at one end against the bearing A3and abutting at its other end on a pin HP' held on the shaft H. Theletthand end of the shaft H normallysupports a starting lever lextending transversely and ulcrumed at I on the main frame A, and thepivotal end ot the starting lever l provided with itorlr inembers I2,I3, ot which the member T3 is provided with an adjusting screw T4, andthe fork members straddle the lower end oit a lifting arm J ulcruined atits lower end at J on the main frame A. The upper end J2 of the liftingarm J is in close proximity to the peripheral it'ace of the reel VpulleyC, as plainly indicated in Fig. 2, but when the shaft H is moved to theright and from under the lever I then the latter in swinging downwardcauses the screw lL to impart a swinging motion to the lifting arm J inthe direction of the arrow c so that the top J2 llt) of the said liftingarm J engages the peripheral face of the reel pulley C and lifts thelatter and with it the reel so that the pulley C moves out of drivingengagement with the pulley B2 (see Fig. 3). VJhen this takes place thereel D comes to a standstill.

In order to move the shaft H to the right against the tension of thespring H2 and with a view to move the left-hand end of its shaft outfrom under the lever I, the following arrangement is made: rlhe heel F2of the drop arm F is provided with a rearward extension F3 (see Figs. 2,3, a and 5) nor mally out of the path of blocks l secured on a slide Karranged parallel to the shaft H and mounted to slide in the directionof its length in the bearings A3, A4 previously mentioned (see Figs. 1and il).

The slide K `receives a continuous reciprocating motion from the reelshaft D as long as the latter is driven and for this purpose thefollowing arrangement is made: On the slide 1 is secured a collar L (seeFigs. l and 6) by the use of a set screw L, and on the collar L isarranged a rearwardly-eXtending pin L2 engaging a forli N forming partof the lower end of a lever N fulcruined at N2 on the main frame A.. Theupper end of the lever N is provided with a fork N3 engaging a crank armO held on the hub O of a gear wheel O2 journaled in suitable bearingsarranged on the main frame A. The gear Wheel O2 is in mesh with a pinionP having a hub P journaled in suitable bearings on the main frame A, andon the hub P is secured a crank arm P2 engaging a cross head Q formed onor attached to a traverse bar Q, mounted to slide in suitable hearingsarranged on the main frame A. The traverse bar Q, is provided with eyesQ2 through which pass the threads or yarns E after passing through theeyes F so that the threads E are properly fed onto the reel D in theusual manner. The pinion P is provided with a bevel gear wheel R (seeFigs. 1 and 6) in mesh with a bevel gear wheel R secured on a shaft R2journaled in suitable bearings arranged on the main frame A, and on thesaid shaft R2 is secured a gear wheel R3 in mesh with a pinion R4secured on the reel shaft D. Now when the reel shaft D is rotated aspreviously explained, then a rotary motion is transmitted by the pinionR4 and gear Wheel to the shaft R2 which by the gear wheels R, R, P andO2 rotates the crank arm O so that a swinging motion is given to thelever N which by its fork N and the pin L2 imparts a sliding motion tothe slide K.

From the foregoing it will be seen that as long as the reel shaft D isrotated a sliding motion is given to the slide K and in case one of thedrop arms F is released by its thread or yarn E and swings downward intothe position shown in Fig. 5 then the extension F3 of this drop arm Fpasses into the path of the adjacent block K of the reciprocating slideK whereby the block K imparts a sliding movement to the extension F3 andconsequently to the bearing H and the shaft or rod H to lift the latterfrom the left to the right in the direction of the arrow b thus movingthe left-hand end of the rod or shaft H out from under the startinglever I. Then this takes place the latter swings downward and therebyimparts a swinging motion to the lifting arm .l so that the latterraises the pulley C o-ut of engagement with the pulley B2 andconsequently further rotation of the reel D ceases. It will be not-icedthat when rotation of the reel D ceases the reciprocating motion of theslide K ceases owing to the fact that the slide is actuated from theshaft D by the mechanism above described.

1n order to prevent the rod or shaft H from turning in its bearings, itis provided with a depending arm H4 having a fork H5 straddling atension rod S, and in order to prevent the slide K from turning an armK2 depends from the slide and is provided with a fork K2 straddling atension rod S. The tension rods S and S are attached to the main frame Aand the threads or yarns E pass around the said tension rods prior topassing to the eyes F of the drop arms F, as will be readily understoodby reference to Fig. 2.

1t is understood that in case any one of the threads or yarns E breaksor the thread runs out from the corresponding spool E then thecorresponding drop arm F swings downward and in doing so its extensionF3 moves into the path of the adjacent block l( of theslide K. As theslide K reciprocates continually it imparts motion to the extension F2of the drop arm F whereby the shaft H is moved to the right and out fromunder the starting lever I. The latter now swings downward and imparts aswinging motion to the lifting arm J in the direction of the arrow a tolift the pulley C out of engagement with the pulley B2 and consequentlyfurther rotation of the reel D ceases. When the broken thread has beenmended and replaced in the eye F of the returned drop arm F then theoperator swings the starting lever I upward so that the member 12 of thesaid lever imparts a rearward swinging motion to the lifting arm J tocause the latter to lower the pulley C until this pulley is again infrictional contact with the peripheral face of the continually rotatingpulley B2. A rotary motion is now again given to the reel D and theslide K is reciprocated.

It is understood that when the drop arm F is swung back into verticalposition and the lever I is raised the left-hand end of the shaft Hagain moves under the lever 1 by the action of the spring H2 so as tosupport the starting lever I in its normal position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
